A influência da gestação sobre a incidência de neoplasias mamárias em cadelas atendidas no Hospital Veterinário/UFPB no período de 2012-2021

Abstract

Breast neoplasms are the most common progressive alterations among bitches. They constitute one of the main diseases that lead to death in the canine species, with an incidence three times higher than in women. In canines, they may present aspects that are similar to those of the human species, including the incidence of the tumor in relation to age, pregnancy and lactation. The increase in the number of pet adoptions, associated to the increase in their life expectancy, configures the relevance of studies that make it possible to improve the knowledge about the diseases that affect these animals as a way to provide them with a better quality of life. This study aimed to evaluate the influence of pregnancy and lactation on the occurrence of mammary neoplasms in bitches treated at the Veterinary Hospital of UFPB. Data were collected from 103 animals seen at the Veterinary Hospital of UFPB. The highest prevalence was found in animals older than five years of age, representing 91.3% of the total. A higher number of animals with no history of lactation was found (63.1%), compared to 36.8% that had lactated and presented mammary tumors. It was also observed that in relation to the number of births, the incidence dropped considerably when the animal had a history of multiparity, indicating the possible influence of these factors that on the incidence of mammary neoplasms in bitches.
